Chapter 444: Star Classification

That's right. After all, installing a circular collider directly on a solar-power satellite to produce antimatter eliminates the problem of power transmission.

Although this will make the satellite larger, it does not matter. Of course, building such a stellar energy collector will take a lot of time and effort.

In fact, if you insist, this stellar energy collector is actually an enlarged version of the Covenant spacecraft, and a short-tail version at that.

When the Wandering Blue Star's Science Academy was designing the stellar energy collector, it fully absorbed the design concept of the Covenant spacecraft's power-generating light sail.

Only after the spacecraft carrying the stellar energy collector reaches the designated location and launches it, will the power-generating light sail be opened.

That's right, in order to save manufacturing costs, the stellar energy collector does not have the function of autonomous flight. Although it has thrusters, they are very low-powered thrusters used to fine-tune the angle.

Therefore, if you want to send the manufactured stellar energy collector from the Blue Planet into orbit around Proxima Centauri, you have to use a transport spacecraft.

Of course, a circular collider with a diameter of 30 kilometers and a length of nearly 100 kilometers, used to produce antimatter, must naturally be disassembled into sections and loaded into spacecraft, and then assembled after flying to the designated star orbit.

After all, the largest transport spacecraft on Wandering Blue Star so far is only ten kilometers long.

The material cannot be too large because the strength cannot withstand it, especially when the spacecraft is turning, the inertia generated will tear the spacecraft apart.

After the assembly is completed, when it starts working, it will extend the mast like the Covenant spacecraft, and then the power-generating light sail like a plastic film will be unfolded by the rope made of nanotubes. In this way, as long as it faces the red dwarf star Proxima Centauri, it can absorb sunlight and generate electricity 24 hours a day.

The electricity generated naturally becomes the energy source for the collider to produce antimatter.

Of course, the reason why we chose the red dwarf star Proxima Centauri instead of the brighter yellow dwarf-level stars Propista AB is naturally because red dwarfs have many advantages except that they are a little dimmer!
As for what is a red dwarf and what is a yellow dwarf, this is naturally the classification made by scientists on the stars in the universe.

You know, the universe is a tightly ordered structure. Galaxies form galaxy clusters, and galaxies themselves are composed of countless star systems.

Every star system has one or more stars as main stars that dominate the operation of the entire star system.

For example, the solar system where the wandering blue planet was originally located was a star system, and the sun was the only star in this star system.

This is different from its good neighbor Proxima Centauri. The star system where Proxima Centauri is located is a star system dominated by three stars.

Stars are celestial bodies in the universe that can shine. The reason they can shine is that violent hydrogen nuclear fusion is always going on inside them. Of course, the intensity of hydrogen nuclear fusion in each star is not the same, which mainly depends on their mass.

Therefore, not all stars are the same. Stars also need to be classified, and different stars have different lifespans and endings.

For example, our sun is a yellow dwarf. It is generally believed that stars with a mass between 80% and 150% of the sun are yellow dwarfs. Yellow dwarfs are not considered larger stars. In fact, they are relatively small. However, the sun is not the smallest star in the universe. There are two types of stars smaller than the sun. One is the orange dwarf. From the name, we can know that its brightness is smaller than the sun and its heat is lower than the sun. The mass of an orange dwarf is generally more than 80% of the sun, and the minimum is not less than 50%.

Because if a star's mass is less than half that of the sun, then it will not even be considered an orange dwarf, it will be defined as a red dwarf, which is the smallest star in the universe.

The red dwarf star closest to the solar system is Proxima Centauri. Its mass is only a little over 12 percent of that of the sun, so it is naturally classified as a red dwarf.

Of course, there are many stars in the universe that are more massive than the sun, and their hydrogen nuclear fusion intensity is much greater than that of the sun.

Sirius is a star that is much larger than the sun, and such stars are called blue dwarfs.

Of course, the final destination of all stars is the same, they will all exhaust their own energy.

But the fate of stars of different levels is not the same. If the mass of a star can reach more than thirty times that of the sun, then after its fuel is exhausted, it will become a mysterious black hole through a dazzling supernova explosion.

If the star's mass is smaller, between thirty and eight times the mass of the sun, it will also explode as a supernova.

However, after the explosion, such a star will not become a black hole, but a neutron star.

A yellow dwarf star of the Sun's magnitude will not experience a supernova explosion. After its fuel is exhausted, it will first expand into a red giant and then collapse into a white dwarf.

Of course, a supernova explosion is not a helium flash, because a supernova explosion is much more powerful than helium flash. A helium flash that can destroy all life in the entire solar system is like the comparison between a little boy and firecrackers in front of a supernova explosion.

Red dwarfs and orange dwarfs that are smaller than the sun don't even have the chance to become white dwarfs. They will quietly become cold black dwarfs.

In fact, the black dwarf is the final destination of all stars. The white dwarf will gradually cool down, and one day, it will lose all its temperature and light. On that day, it will truly become a black dwarf. The same is true for neutron stars. The residual temperature of the star will always dissipate, and the black dwarf is also its final destination.

Of course, it's not just neutron stars, even black holes are no exception. According to Hawking radiation theory, if a black hole stops swallowing, the matter inside it will gradually evaporate. Although this evaporation process is extremely long, perhaps hundreds of billions of years, or trillions of years, or even longer, but in theory, it will eventually become a black dwarf.

However, there is no real black dwarf in the universe so far. This is because the cooling time of a star is very slow, usually taking tens of billions of years.

Low-mass stars such as red dwarfs and orange dwarfs have extremely long lifespans, which can reach hundreds of billions of years, because the lifespan of a star is determined by the intensity of hydrogen nuclear fusion.

The more intense the fusion, the shorter the lifespan. The intensity of hydrogen nuclear fusion is determined by mass. The smaller the mass, the weaker the intensity. Therefore, small stars that can directly become black dwarfs have extremely long lifespans. The lifespan of our universe is only more than 10 billion years, so there are no black dwarfs in the universe so far.

Of course, the main reason for choosing the red dwarf star Proxima Centauri is the safety of the power-generating light sail of the stellar energy collector.

After all, the previous example of the Covenant is still there! If the Covenant had not been affected by the solar storm, there would be no way to prevent it from happening. The power generating sails of the stellar energy collector are relatively fragile!
